RECONSTRUCTION OF LEADING PARTS OF CONVEYORS PD 710, 711, 714, 755 - NOEN, a.s.

General description

The purpose of additional tensioning in the leading part of the driving station is to extend the total tensioning path of the tensioning system for the conveyor belt.

The tensioning path of the basic tensioning mechanism in the driving station is designed for an “St” type conveyor belt. In case that a new “PA” type conveyor belt is used, the original length of a tensioning path of conveyors longer than 1,000 m is insufficient. It is necessary to use the leading part with additional tensioning.

The second tensioning loop is formed in the leading part on the conveyor belt, with a tension carriage, a reversing drum, and two transferring rollers and this loop covers the missing tensioning path.

Tensioning of the belt in the leading part is only performed, when the conveyor is stopped. After having been tensioned, the tension carriage of the additional tensioning is mechanically locked in a fixed position. Only then, the conveyor can be finally tensioned to operating parameters using the main tensioning mechanism in the driving station, thereby to secure conditions for startup and operation.
